Officials with the Baltimore County Health Department say about a dozen people reported feeling ill at a Johns Hopkins building Monday.
Of the 11 employees reporting sickness, several were transported to local hospitals with symptoms of nausea, dizziness and headache.
The location is that of the Keswick South building, the same building that was evacuated last week as several people complained of nausea and dizziness.
The Keswick South building is a hospital administration building/office.
BCHD is working in coordination with state health, emergency management and Johns Hopkins to investigate. City and state health officials are on scene and are conducting tests of the water supply at multiple locations throughout the south building.
